Feat ERC7715 grant_permissions support on lab

[KannuSingh]

Description

This PR is enabling support for ERC 7715 new JSON-RPC method wallet_grantPermissions for DApp to request permissions from a wallet in order to execute transactions on users’s behalf. This enables :

• Executing transactions for users without a wallet connection.

The PR would need addition of one manadory .env values NEXT_PUBLIC_PIMLICO_KEY which is used to submit userOperation.

This PR also enable testing this on a local AA infra running over forked sepolia chain.
For more information on how to set up local testing, refer to how to setup local-testing.

When running the project locally and wanting to use the local forked network and AA setup, just add the .env variable values, and the project will automatically use the local setup:

NEXT_PUBLIC_LOCAL_BUNDLER_URL=
NEXT_PUBLIC_LOCAL_PAYMASTER_URL=
NEXT_PUBLIC_LOCAL_CLIENT_URL=

PR is missing description

should we remove this at some point?

@lukaisailovic do we want a test for this? It's not appkit specific behavior but if we want it to be tested it would require a playwright test

@tomiir I don't think its necessary now, since its not a part of AppKit. This is the preparation for integration of Sessions in our Universal Wallet. At that point we will add tests.

If we don't pass any other fields here, we don't have to destruct the object and directly use the ref. (In case it's not required for cloning object purposes)

Suggested change

	const userOpHash = getUserOperationHash({
	userOperation: {
	...userOp
	},
	const userOpHash = getUserOperationHash({
	userOperation: userOp,

My only question is: do we need to clear the signer when the user disconnects?
Else looks good!
